In the step (3), the drying treatment temperature is 150 ℃.
In the step (5), the mass percentage concentration of the water-soluble ceramic precursor aqueous solution is 15%.
Example 2
The filler for the water-soluble mold in the embodiment is one or a mixture of micron-sized silicon dioxide, micron-sized aluminum oxide and micron-sized titanium dioxide hollow ceramic microspheres. The other components are the same as those in the first embodiment.

The rest is the same as example 1.
Example 7
Referring to fig. 1, the method for manufacturing a water-soluble mold according to the present embodiment is implemented as follows:
step one, batching: dissolving a water-soluble ceramic precursor with a main chain of-O-Ti-O-structure in water to prepare a water solution with the concentration of 10%, adding a water-soluble mold filler after the water-soluble ceramic precursor is completely dissolved, wherein the mass of the water-soluble ceramic precursor water solution is 15% of that of the water-soluble mold filler, and uniformly stirring to prepare a water-soluble mold material;
step two, preforming: putting the water-soluble mould material prepared in the step one into a mould for preparing a water-soluble mould or a core mould, and compacting to prepare the required shape of the water-soluble mould (the core mould), so that the workload of machining can be reduced; or the water-soluble mould material prepared in the step one is made into a preformed block, and the required shape of the water-soluble mould (core mould) is prepared by various machining means; in the preforming process, the larger the pressure applied to the die material is, the stronger the pressure resistance of the manufactured core die is;
step three, drying: drying the preformed water-soluble mould prepared in the third step at the drying temperature of 100 ℃ until the preformed water-soluble mould is dried to prepare a formed water-soluble mould; the drying time depends on the size of the sample to be dried, and the larger the size of the sample, the longer the drying time is needed; during drying, the preformed core mold can be placed into a drying oven for drying; the moisture in the composite must be completely dried out by drying, otherwise the performance of the composite is affected;
step four, machining: machining the surface of the pre-formed water-soluble mould after drying to obtain a water-soluble mould (core mould) with a precise geometric dimension; the pre-forming block can be processed by various machining means, and can be processed into various required shapes including various arcs; during machining, the direction of the cutter entering is taken into consideration, so that defects at edges and corners are avoided;
step five, surface treatment: coating a layer of water-soluble ceramic precursor water solution with the mass percentage concentration of 20% on the outer surface of the water-soluble mould (core mould) after machining, and drying, wherein the dried coating forms a hard protective film on the outer surface of the water-soluble mould (core mould); the desired water-soluble mold (mandrel) is produced.
The purpose of surface treatment after the mandrel is processed into a required shape is as follows: so as to avoid the problem that glue (the glue on the prepreg for composite material molding) seeps into tiny gaps of the water-soluble core mold material in the curing process and brings difficulty to the removal of the core mold material.
The water-soluble molds obtained in examples 1 to 7 were tested, heated to 500 deg.C, 600 deg.C, and 800 deg.C, respectively, and the dissolved state thereof was recorded, and the specific results are shown in Table 1, and the molds of examples 1 to 7 were tested for their compressive strength using a cube having a side length of 25.4mm, and the strength retention rates at 100 deg.C, 200 deg.C, and 300 deg.C were recorded, and the results are shown in Table 2.
